Revised Simplified Formulae for Calculating the Speed of Sound in Sea Water.

Abstract

Recently-published data on the speed of sound in water as a function of temperature, salinity, and pressure reveal significant differences from former data. In the present memorandum a number of simple equations are developed from the new data. Sound speeds calculated using these equations are shown to be in agreement with the new data to within 0.1 m/s over a wide range of temperatures and salinities at atmospheric pressure, and to within 0.5 m/s at great depths. It is also shown that the disagreement between experiments is of such magnitude as not to merit equations any more precise than those developed herein.
